Pooling and Servicing Agreement, dated as of November 1, 2015, among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Xxxxx Fargo Bank, National Association, as Master Servicer, Midland Loan Services, a Division of PNC Bank, National Association, as Special Servicer, Pentalpha Surveillance LLC, as Operating Advisor, Xxxxx Fargo Bank, National Association, as Certificate Administrator, and Wilmington Trust, National Association, as Trustee.

PRELIMINARY STATEMENT:

(Terms used but not defined in this Preliminary
Statement shall have the meanings
specified in Article I hereof)

The Depositor intends to sell pass-through certificates to be issued hereunder in multiple classes which in the aggregate will evidence the entire beneficial ownership interest in the Trust Fund consisting primarily of the Mortgage Loans. As provided herein, the Certificate Administrator will elect that two segregated portions of the Trust Fund be treated for federal income tax purposes as two separate REMICs (each, a “Trust REMIC” or, in the alternative, the “Upper-Tier REMIC” and the “Lower-Tier REMIC”, respectively). The Class X-0, Xxxxx X-0, Class X-0, Xxxxx X-0, Class A-SB, Class A-S, Class B, Class C, Class D, Class X-D, Class E, Class F, Class G, Class NR, Class X-A, Class X-B, Class X-F, Class X-G and Class X-NR Certificates will represent “regular interests” in the Upper-Tier REMIC and the Upper-Tier Residual Interest will represent the sole class of “residual interests” in the Upper-Tier REMIC.

There are also (i) 13 classes of uncertificated Lower-Tier Regular Interests issued under this Agreement (the Class XX-0, Xxxxx XX-0, Class LA-3, Class LA-4, Class LA-SB, Class LA-S, Class LB, Class LC, Class LD, Class LE, Class LF, Class LG and Class LNR Interests), each of which will constitute a class of “regular interests” in the Lower-Tier REMIC, and (ii) the Lower-Tier Residual Interest, which will represent the sole class of “residual interests” in the Lower-Tier REMIC.

The Lower-Tier Regular Interests will be held by the Trustee as assets of the Upper-Tier REMIC. The Class R Certificates will represent both the Lower-Tier Residual Interest and the Upper-Tier Residual Interest.

UPPER-TIER REMIC

The following table sets forth the Class designation, the approximate initial pass-through rate (the “Pass-Through Rate”), the aggregate initial principal balance (the “Original Certificate Principal Balance”) or, in the case of the Class X-A, Class X-B, Class X-D, Class X-F, Class X-G and Class X-NR Certificates, notional amount (the “Original Notional Amount”), as applicable, and the initial ratings given each Class by the Rating Agencies (the “Original Ratings”) for each Class of Certificates comprising or evidencing the interests in the Upper-Tier REMIC created hereunder:

(1)

The Certificates marked with “NR” have not been rated by the applicable Rating Agency.

(2)

The Class X-A Pass-Through Rate is variable and, for each Distribution Date, will equal the weighted average of the Class X Strip Rates for the Class A-1, Class A-2, Class A-3, Class A-4, Class A-SB and Class A-S Components for such Distribution Date (weighted on the basis of the respective Component Notional Amounts of such Components immediately prior to such Distribution Date). The Class X-B Pass-Through Rate is fixed and, for each Distribution Date, will equal the Class X Strip Rate for the Class B Component for such Distribution Date. The Class X-D Certificates will not have a Pass-Through Rate, but will be entitled to receive the sum of the interest distributable on the Class X-D Components. The Pass-Through Rate for the Class D Component of the Class X-D Certificates is fixed and, for each Distribution Date, will equal the Class X Strip Rate for the Class D Component for such Distribution Date. The Pass-Through Rate for Class E Component of the Class X-D Certificates is fixed and, for each Distribution Date, will equal the Class X Strip Rate for the Class E Component for such Distribution Date. The Class X-F Pass-Through Rate is variable and, for each Distribution Date, will equal the Class X Strip Rate for the Class F Component for such Distribution Date. The Class X-G Pass-Through Rate is variable and, for each Distribution Date, will equal the Class X Strip Rate for the Class G Component for such Distribution Date. The Class X-NR Pass-Through Rate is variable and, for each Distribution Date, will equal the Class X Strip Rate for the Class NR Component for such Distribution Date.

(3)

The Class X-A, Class X-B, Class X-F, Class X-G and Class X-NR Certificates will not have Certificate Principal Balances; rather, each such Class of Certificates will accrue interest as provided herein on the related Notional Amount. The Class X-D Certificates will not have a Certificate Principal Balance and will receive interest that accrues on the Class D Component and Class E Component.

(4)

The Class R Certificates do not have a Certificate Principal Balance or Notional Amount, do not bear interest and will not be entitled to distributions of Yield Maintenance Charges. Any Available Funds remaining in the

-2-

Lower-Tier Distribution Account and the Upper-Tier Distribution Account, after all required distributions under this Agreement have been made to the Holders of the Regular Certificates, will be distributed to the Holders of the Class R Certificates.

LOWER-TIER REMIC

The following table sets forth the Class designation, the original Lower-Tier Principal Balance, the corresponding Class of Regular Certificates (the “Corresponding Certificates”) and the corresponding component of the Class X Certificates (the “Corresponding Component”) for each Lower Tier Regular Interest.

Class Designation⁽¹⁾⁽²⁾	Original Lower-Tier Principal Balance		Corresponding Certificate	Corresponding Component⁽²⁾

Class LNR		$ 43,458,786	Class NR	Class NR

(1)

The interest rate of each Lower-Tier Regular Interest is the WAC Rate.

(2)

Each Lower-Tier Regular Interest is also the “Corresponding Lower-Tier Regular Interest” with respect to the Corresponding Certificate and the Corresponding Component, each Corresponding Certificate is the Corresponding Certificate with respect to the Corresponding Component and each Corresponding Component is the Corresponding Component with respect to the Corresponding Certificates.

The Certificate Principal Balance of any Class of Principal Balance Certificates outstanding at any time represents the maximum amount which holders thereof are then entitled to receive as distributions allocable to principal from the cash flow on the Mortgage Loans and the other assets in the Trust Fund; provided, however, that in the event that amounts previously allocated as Realized Losses to a Class of Principal Balance Certificates in reduction of the Certificate Principal Balance thereof are recovered subsequent to the reduction of the Certificate Principal Balance of such Class to zero, such Class may receive distributions in respect of such recoveries in accordance with the priorities set forth in Section 4.01 of this Agreement. As of the Cut-Off Date, the Mortgage Loans have an aggregate Stated Principal Balance equal to approximately $939,639,786.

In consideration of the mutual agreements herein contained, the Depositor, the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator and the Trustee agree as follows:

Amount is required to be calculated, an amount (subject to the operation of the final paragraph of Section 3.10(a)) equal to the excess, if any, of (a) the Stated Principal Balance of such Mortgage Loan (or Serviced Whole Loan) as of the last day of the related Collection Period over (b) the excess of (i) the sum of (A) 90% of the appraised value of the related Mortgaged Property or Properties (as determined by one or more Appraisals obtained by the Special Servicer (the cost of which shall be advanced by the Master Servicer as a Property Advance unless such Property Advance would be a Nonrecoverable Advance)), minus such downward adjustments as the Special Servicer may make in accordance with the Servicing Standard (without implying any obligation to do so) based upon the Special Servicer’s review of the Appraisal and such other information as the Special Servicer may deem appropriate and (B) all escrows, letters of credit and reserves in respect of such Mortgage Loan (or Serviced Whole Loan) as of the date of the calculation over (ii) the sum, as of the Due Date occurring in the month of the date of determination of, (A) to the extent not previously advanced by the Master Servicer or the Trustee, all unpaid interest on such Mortgage Loan (or Serviced Whole Loan, if applicable) at a per annum rate equal to its Mortgage Loan Rate (and with respect to a Serviced Whole Loan, interest on the related Serviced Companion Loan(s) at the related Mortgage Loan Rate), (B) all unreimbursed Advances (which shall include, without limitation, (1) any Advances as to which the advancing party was reimbursed from a source other than the related Mortgagor and (2) any Unliquidated Advances), with interest thereon at the Advance Rate in respect of such Mortgage Loan (or Serviced Whole Loan) and (C) all currently due and unpaid real estate taxes and assessments, insurance premiums and ground rents, unpaid Special Servicing Fees and all other amounts, due and unpaid with respect to such Mortgage Loan (or Serviced Whole Loan) (which taxes, premiums, ground rents and other amounts have not been the subject of an Advance by the Master Servicer or the Trustee, as applicable, and/or for which funds have not been escrowed). Promptly upon the occurrence of an Appraisal Reduction Event (or a longer period so long as the Special Servicer is (as certified thereby to the Trustee in writing) diligently and in good faith proceeding to obtain such), if an Appraisal has not been obtained within the immediately preceding nine (9) months (or if the Special Servicer has determined in accordance with the Servicing Standard such Appraisal to be materially inaccurate), the Special Servicer shall obtain an Appraisal, the costs of which shall be paid by the Master Servicer as a Property Advance (or as an expense of the Trust Fund and paid by the Master Servicer out of the Collection Account if such Property Advance would be a Nonrecoverable Advance). The Master Servicer shall provide (via electronic delivery) the Special Servicer with information in its possession that the Special Servicer reasonably requires to calculate or recalculate any Appraisal Reduction Amount pursuant to the definition thereof using reasonable efforts to deliver such information within four (4) Business Days of the Special Servicer’s reasonable written request.

Notwithstanding the foregoing, if an Appraisal is required to be obtained in accordance with Section 3.10(a) of this Agreement but is not obtained within 120 days following the events described in the applicable clause of the definition “Appraisal Reduction Event” (without regard to the time periods stated therein), then, until such Appraisal is obtained and solely for purposes of determining the amounts of P&I Advances, the Appraisal

-8-

Reduction Amount will equal 25% of the Stated Principal Balance of the related Mortgage Loan; provided that, upon receipt of an Appraisal by the Special Servicer, however, the Appraisal Reduction Amount for such Mortgage Loan (or the related Serviced Whole Loan, if applicable) will be recalculated in accordance with this definition without regard to this sentence. With respect to each Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan as to which an Appraisal Reduction Event has occurred (unless the Mortgage Loan (or Serviced Whole Loan) has become a Corrected Mortgage Loan (if a Servicing Transfer Event had occurred with respect to the related Mortgage Loan (or Serviced Whole Loan)) and has remained current for three consecutive Monthly Payments, and with respect to which no other Appraisal Reduction Event has occurred with respect thereto during the preceding three months), the Special Servicer shall, within 30 days of each anniversary of such Appraisal Reduction Event, order an Appraisal (which may be an update of the prior Appraisal) (the cost of which will be covered by, and reimbursable as, a Property Advance by the Master Servicer or as an expense of the Trust Fund and paid by the Master Servicer out of the Collection Account if such Property Advance would be a Nonrecoverable Advance), provided, however, that no new or updated Appraisal will be required if the Mortgage Loan, Serviced Whole Loan or REO Property is under contract to be sold within 90 days of such Appraisal Reduction Event or anniversary thereof and the Special Servicer reasonably believes such sale is likely to close. Based upon such Appraisal or letter updates thereto, the Special Servicer shall determine and report to the Master Servicer and the Certificate Administrator the Appraisal Reduction Amount, if any, with respect to such Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan and, in the case of a Whole Loan, determined in accordance with the Co-Lender Agreement, and each of the Master Servicer and the Certificate Administrator shall be entitled to rely conclusively on such determination by the Special Servicer. Upon completion, the Special Servicer shall deliver a copy of any such Appraisal to the Master Servicer and the Certificate Administrator, which shall be in electronic format. Each Appraisal Reduction Amount shall also be adjusted with respect to the next Distribution Date to take into account any subsequent Appraisal and annual letter updates, as of the date of each such subsequent Appraisal or letter update.

Upon payment in full or liquidation of any Mortgage Loan (other than a Non-Serviced Mortgage Loan) or Serviced Whole Loan for which an Appraisal Reduction Amount has been determined, such Appraisal Reduction Amount will be eliminated. In addition, with respect to any Mortgage Loan (or Serviced Whole Loan, but not including any Non-Serviced Mortgage Loan), as to which an Appraisal Reduction Event has occurred, such Mortgage Loan (or Serviced Whole Loan) shall no longer be subject to the Appraisal Reduction Amount if (a) such Mortgage Loan (or Serviced Whole Loan) has become a Corrected Mortgage Loan (if a Servicing Transfer Event had occurred with respect to the related Mortgage Loan (or Serviced Whole Loan)) and such Mortgage Loan (or Serviced Whole Loan) becomes and remains current for three consecutive Monthly Payments and (b) no other Appraisal Reduction Event has occurred and is continuing.

If an Appraisal Reduction Event occurs with respect to any Mortgage Loan that is part of a Serviced Whole Loan, then an Appraisal Reduction Event shall be deemed to also have occurred with respect to each related Serviced Companion Loan. If an Appraisal Reduction Event occurs with respect to any Serviced Companion Loan, then an Appraisal Reduction Event shall be deemed to also have occurred with respect to the related Mortgage Loan that is part of a Serviced Whole Loan. No Appraisal Reduction Event may occur at any time when the aggregate Certificate Principal Balance of all Classes of Principal Balance Certificates (other than the Class A Certificates) has been reduced to zero.

Each assignment referred to in the prior paragraph that is recorded and the file copy of each UCC-3 assignment referred to in the previous paragraph shall reflect that it should be returned by the public recording or filing office to the Custodian or its agent following recording (or, alternatively, to the applicable Mortgage Loan Seller or its designee, in which case the applicable Mortgage Loan Seller shall deliver or cause the delivery of the recorded/filed original to the Custodian promptly following receipt); provided that, in those instances where the public recording office retains the original assignment of Mortgage or assignment of Assignment of Leases, the Custodian shall obtain therefrom a certified copy of the recorded original.

If the Custodian has received written notice that any of the aforementioned assignments is lost or returned unrecorded or unfiled, as the case may be, because of a defect therein, then the Custodian shall direct the applicable Mortgage Loan Seller (pursuant to the Loan Purchase Agreement) promptly to prepare or cause the preparation of a substitute therefor or to cure such defect, as the case may be, and the Mortgage Loan Seller shall record or file, or cause AMO to record or file, or with respect to any assignments the Custodian has agreed to file as described above, to deliver to the Custodian the substitute or corrected document. The Custodian shall upon receipt from the applicable Mortgage Loan Seller cause the same to be duly recorded or filed, as appropriate.

(d) In connection with the Depositor’s assignment pursuant to Section 2.01(a) of this Agreement, except with respect to any Non-Serviced Mortgage Loan, the Depositor shall direct the applicable Mortgage Loan Seller (pursuant to the related Loan Purchase Agreement) to deliver to and deposit (or cause to be delivered and deposited) with the Master Servicer within five (5) Business Days after the Closing Date, (i) all documents and records not otherwise required to be contained in the Mortgage File that (A) relate to the origination and/or servicing and administration of the Mortgage Loans or any related Serviced Companion Loan, (B) are reasonably necessary for the ongoing administration and/or servicing of the Mortgage Loans

-108-

(including any asset summaries related to the Mortgage Loans that were delivered to the Rating Agencies in connection with the rating of the Certificates) and the Serviced Companion Loans or for evidencing or enforcing any of the rights of the holder of the Mortgage Loans and the Serviced Companion Loans or holders of interests therein and (C) are in the possession or under the control of the applicable Mortgage Loan Seller, together with (ii) all unapplied Escrow Payments and reserve funds in the possession or under the control of the applicable Mortgage Loan Seller that relate to such Mortgage Loans or any related Serviced Companion Loans, provided that copies of any document in the Mortgage File and any other document, record or item referred to above in this sentence that constitutes a Designated Servicing Document shall be delivered to the Master Servicer on or before the Closing Date; provided, further, that the applicable Mortgage Loan Seller shall not be required to deliver any draft documents, privileged or other communications, credit underwriting, due diligence analyses or data, or internal worksheets, memoranda, communications or evaluations. In addition, attached as Exhibit P to this Agreement is the Supplemental Servicer Schedule. The Master Servicer shall hold all such documents, records and funds on behalf of the Trustee in trust for the benefit of the Certificateholders (and, insofar as they also relate to the Serviced Companion Loan, on behalf of and for the benefit of the applicable Companion Loan Holder).

Each Loan Purchase Agreement shall generally provide that as long as any Certificate is outstanding, the Seller shall, upon reasonable notice, reasonably cooperate with the Trustee, the Master Servicer, the Special Servicer, the Custodian and/or the Depositor, as applicable, to provide all items in the Mortgage Files and execute and/or deliver any documents that are necessary to effect the delivery, assignment and/or recordation of any document relating to the Mortgage Loans at the time required for enforcement by the Trust.

(e) In connection with the Depositor’s assignment pursuant to subsection (a) above, the Depositor shall deliver, and hereby represents and warrants that it has delivered, to the Custodian and the Master Servicer, on or before the Closing Date, a fully executed original counterpart of each Loan Purchase Agreement, as in full force and effect, without amendment or modification, on the Closing Date.

(f) The Custodian with respect to the Serviced Whole Loans, shall also hold the related Mortgage File for the use and benefit of the Companion Loan Holders.

(g) The parties to this Agreement acknowledge and agree, with respect to each Mortgage Loan that is part of a Serviced Whole Loan and a Non-Serviced Mortgage Loan, that the Trust assumes the obligations and rights of the holder of such Mortgage Loan under the respective Co-Lender Agreement and any applicable Other Pooling and Servicing Agreement.

(h) It is not intended that this Agreement create a partnership or a joint-stock association.

(i) With respect to the Mortgage Loans secured by the Mortgaged Properties identified as Aloft Hotel - Downtown Denver, Country Inn & Suites BWI, Hampton Inn Henderson NC, Homewood Suites - Brownsville and Country Inn & Suites Augusta on the Mortgage Loan Schedule, which are each subject to one or more franchise agreements, each with a related comfort letter in favor of the respective Mortgage Loan Seller that requires notice to or

-109-

request of the related franchisor to transfer or assign any related comfort letter to the Trust or otherwise have a new comfort letter issued in the name of the Trust, the related Mortgage Loan Seller or its designee will be required in the related Loan Purchase Agreement to provide any such required notice or make any such required request to the related franchisor (with a copy of such notice or request to the Master Servicer) within 45 days of the Closing Date (or any shorter period if required by the applicable comfort letter), and the Master Servicer shall use reasonable efforts in accordance with the Servicing Standard to acquire such replacement comfort letter, if necessary (or to acquire any such new document or acknowledgement as may be contemplated under the existing comfort letter).

Section 2.02 Acceptance by the Trustee, the Custodian and the Certificate Administrator.

(a) The Trustee, by its execution and delivery of this Agreement, hereby accepts receipt, directly or through the Custodian on its behalf, of (i) the Mortgage Loans and all documents delivered to it that constitute portions of the related Mortgage Files and (ii) all other assets delivered to it and included in the Trust Fund, in good faith and without notice of any adverse claim, and declares that it or the Custodian on its behalf holds and will hold such documents and any other documents subsequently received by it that constitute portions of the Mortgage Files, and that the Custodian on behalf of the Trustee holds and will hold the Mortgage Loans and such other assets, together with any other assets subsequently delivered to it that are to be included in the Trust Fund, in trust for the exclusive use and benefit of all present and future Certificateholders and, if applicable, the Companion Loan Holders pursuant to Section 2.01(f) of this Agreement. With respect to each Serviced Whole Loan, the Custodian shall also hold the portion of such Mortgage File that relates to the Companion Loan in such Serviced Whole Loan in trust for the use and benefit of the related Companion Loan Holder. In connection with the foregoing, the Custodian hereby certifies to each of the other parties hereto, the applicable Mortgage Loan Seller, each Underwriter and each Initial Purchaser that, as to each Mortgage Loan, (i) all documents specified in clause (l) of the definition of “Mortgage File” are in its possession or the possession of the Custodian on its behalf, and (ii) the original Note(s) (or, if accompanied by a lost note affidavit, the copy of such Note(s)) received by it or the Custodian with respect to such Mortgage Loan has been reviewed by it or by the Custodian on its behalf and (A) appears regular on its face (handwritten additions, changes or corrections shall not constitute irregularities if initialed by the Mortgagor), (B) appears to have been executed (where appropriate) and (C) purports to relate to such Mortgage Loan.

(b) On or about the 60^th day following the Closing Date (and, if any exceptions are noted, again on or about the 90^th day following the Closing Date and monthly thereafter until the earliest of (i) the second anniversary of the Closing Date, (ii) the day on which all material exceptions have been removed and (iii) the day on which the applicable Mortgage Loan Seller has repurchased or substituted for the last affected Mortgage Loan), the Custodian shall review the documents delivered to it with respect to each Mortgage Loan, and the Custodian shall, subject to Section 2.01(c), Section 2.02(c) and Section 2.02(d) of this Agreement and the terms of the respective Loan Purchase Agreements, certify in writing (substantially in the form of Exhibit N to this Agreement) to each of the other parties hereto, the applicable Mortgage Loan Seller, each Underwriter and each Initial Purchaser (and upon request, in the case of a Serviced Whole Loan, to the related Companion Loan Holder) that, as to each

-110-

Mortgage Loan then subject to this Agreement (except as specifically identified in any exception report annexed to such certification, which exception report (and any updates thereto) shall also be electronically delivered in Excel-compatible format): (i) all documents specified in clauses (1), (2), (3), (4) (other than with respect to a Non-Serviced Mortgage Loan), (5), (7), (15) and (20) (for any Mortgage Loan that is part of a Whole Loan) of the definition of “Mortgage File” are in its possession or the related Mortgage Loan Seller has otherwise satisfied the delivery requirements in accordance with the related Loan Purchase Agreement; (ii) the recordation/filing contemplated by Section 2.01(c) of this Agreement has been completed (based solely on receipt by the Custodian of the particular recorded/filed documents); (iii) all documents received by it or the Custodian with respect to such Mortgage Loan have been reviewed by it or the Custodian on its behalf and (A) appear regular on their face (handwritten additions, changes or corrections shall not constitute irregularities if initialed by the Mortgagor), (B) appear to have been executed (where appropriate) and (C) purport to relate to such Mortgage Loan; and (iv) based on the examinations referred to in Section 2.02(a) of this Agreement and this Section 2.02(b) and only as to the foregoing documents (together with any Loan Agreement that has been delivered by the related Mortgage Loan Seller), the information set forth in the Mortgage Loan Schedule with respect to the items specified in clauses (iv) and (v)(B) of the definition of “Mortgage Loan Schedule” accurately reflects the information set forth in the Mortgage File. With respect to the items listed in clauses (2), (3), (4) and (6) of the definition of “Mortgage File” if the original of such document is not in the Custodian’s possession because it has not been returned from the applicable recording office, then the Custodian’s certification prepared pursuant to this Section 2.02(b) should indicate the absence of such original. If the Custodian’s obligation to deliver the certifications contemplated in this subsection terminates because two years have elapsed since the Closing Date, the Custodian shall deliver a comparable certification to any party hereto, the related Companion Loan Holder and any Underwriter and any Initial Purchaser on request.

(c) It is acknowledged that none of the Trustee, the Master Servicer, the Special Servicer, the Certificate Administrator or the Custodian is under any duty or obligation to inspect, review or examine any of the documents, instruments, certificates or other papers relating to the Loans delivered to it to determine that the same are valid, legal, effective, genuine, binding, enforceable, sufficient or appropriate for the represented purpose or that they are other than what they purport to be on their face. Furthermore, none of the Trustee, the Master Servicer, the Special Servicer, the Certificate Administrator or the Custodian shall have any responsibility for determining whether the text of any assignment or endorsement is in proper or recordable form, whether the requisite recording of any document is in accordance with the requirements of any applicable jurisdiction, or whether a blanket assignment is permitted in any applicable jurisdiction.

(d) It is understood that the scope of the Custodian’s review of the Mortgage Files is limited solely to confirming that the documents specified in clauses (1), (2), (3), (4) (other than with respect to a Non-Serviced Mortgage Loan), (5), (7), (15) and (20) (for any Mortgage Loan that is part of a Whole Loan) of the definition of “Mortgage File” have been received, appear regular on their face and such additional information as will be necessary for delivering the certifications required by Section 2.02(a) and 2.02(b) of this Agreement.

-111-

(e) If, after the Closing Date, the Depositor comes into possession of any documents or records that constitute part of the Mortgage File or Servicing File for any Mortgage Loan, the Depositor shall promptly deliver such document to the Custodian with a copy to the Master Servicer (if it constitutes part of the Servicing File).

Section 2.03 Mortgage Loan Sellers’ Repurchase, Substitution or Cures of Mortgage Loans for Document Defects in Mortgage Files and Breaches of Representations and Warranties.

(a) If (i) any party hereto (A) discovers or receives notice alleging that any document constituting a part of a Mortgage File has not been properly executed, is missing, contains information that does not conform in any material respect with the corresponding information set forth in the Mortgage Loan Schedule, or does not appear to be regular on its face (each, a “Document Defect”), or (B) discovers or receives notice alleging a breach of any representation or warranty of the applicable Mortgage Loan Seller made pursuant to Section 6(c) of the related Loan Purchase Agreement with respect to any Mortgage Loan (a “Breach”), or (ii) the Special Servicer or the Depositor receives a Repurchase Communication of a request or demand for repurchase or replacement of any Mortgage Loan alleging a Document Defect or Breach (any such request or demand, a “Repurchase Request”), then such Person shall give prompt written notice thereof to the applicable Mortgage Loan Seller, the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event), the other parties hereto, any related Companion Loan Holder (if applicable) and, for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section 11.13 of this Agreement, the Rule 17g-5 Information Provider (to the extent notice has not previously been delivered to such Persons pursuant to this sentence). If any such Document Defect or Breach materially and adversely affects, or any such Document Defect is deemed in accordance with Section 2.03(b) of this Agreement to materially and adversely affect, the value of the related Mortgage Loan (or any related REO Property) or the interests of the Certificateholders therein or causes any Mortgage Loan to fail to be a Qualified Mortgage, (then such Document Defect shall constitute a “Material Document Defect” or such Breach shall constitute a “Material Breach”), as the case may be. The Special Servicer shall determine in its reasonable, good faith discretion and in accordance with the Servicing Standard, with respect to any affected Mortgage Loan or REO Mortgage Loan, whether a Document Defect is a Material Document Defect or a Breach is a Material Breach. If such Document Defect or Breach has been determined to be a Material Document Defect or Material Breach, then the Special Servicer shall give prompt written notice thereof to the applicable Mortgage Loan Seller, the other parties hereto and the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event). Promptly upon becoming aware of any Material Document Defect or Material Breach (including through a written notice given by the Master Servicer or the Special Servicer, as provided above), the Master Servicer, if relating to a Non-Specially Serviced Loan, or the Special Servicer, if relating to a Specially Serviced Loan, shall require the applicable Mortgage Loan Seller, not later than 90 days from the earlier of the applicable Mortgage Loan Seller’s discovery or receipt of notice of, and receipt of a demand to take action with respect to, such Material Document Defect or Material Breach, as the case may be (or, in the case of a Material Document Defect or Material Breach relating to a Mortgage Loan not being a Qualified Mortgage, not later than 90 days from any party discovering such Material Document Defect or Material Breach), to cure the same in all material respects (which cure shall include payment of losses and any

-112-

Additional Trust Fund Expenses associated therewith) or, if such Material Document Defect or Material Breach, as the case may be, cannot be cured within such 90 day period, either to (before the end of such 90 day period) (i) repurchase the affected Mortgage Loan or any related REO Property (or the Trust’s interest therein with respect to any Mortgage Loan that is part of a Whole Loan) at the applicable Purchase Price by wire transfer of immediately available funds to the Collection Account or (ii) substitute a Qualified Substitute Mortgage Loan for such affected Mortgage Loan (provided that in no event shall any such substitution occur on or after the second anniversary of the Closing Date) and pay the Master Servicer for deposit into the Collection Account, any Substitution Shortfall Amount in connection therewith, all in conformity with the applicable Loan Purchase Agreement and this Agreement; provided, however, that if (i) such Material Document Defect or Material Breach is capable of being cured but not within such 90 day period, (ii) such Material Document Defect or Material Breach is not related to any Mortgage Loan’s not being a Qualified Mortgage and (iii) the applicable Mortgage Loan Seller has commenced and is diligently proceeding with the cure of such Material Document Defect or Material Breach within such 90 day period, then such Mortgage Loan Seller shall have an additional 90 days to complete such cure or, in the event of a failure to so cure, to complete such repurchase or substitution (it being understood and agreed that, in connection with such Mortgage Loan Seller’s receiving such additional 90 day period, such Mortgage Loan Seller shall deliver an Officer’s Certificate to the Trustee, the Master Servicer, the Special Servicer and the Certificate Administrator setting forth the reasons such Material Document Defect or Material Breach is not capable of being cured within the initial 90 day period and what actions such Mortgage Loan Seller is pursuing in connection with the cure thereof and stating that such Mortgage Loan Seller anticipates that such Material Document Defect or Material Breach will be cured within such additional 90 day period); and provided, further, that, if any such Material Document Defect is still not cured after the initial 90 day period and any such additional 90 day period solely due to the failure of such Mortgage Loan Seller to have received the recorded document, then such Mortgage Loan Seller shall be entitled to continue to defer its cure, repurchase and substitution obligations in respect of such Document Defect so long as such Mortgage Loan Seller certifies to the Trustee, the Master Servicer, the Special Servicer and the Certificate Administrator every 30 days thereafter that the Document Defect is still in effect solely because of its failure to have received the recorded document and that such Mortgage Loan Seller is diligently pursuing the cure of such defect (specifying the actions being taken), except that no such deferral of cure, repurchase or substitution may continue beyond the date that is 18 months following the Closing Date. If the affected Mortgage Loan is to be repurchased, the Master Servicer shall designate the Collection Account as the account to which funds in the amount of the Purchase Price are to be wired. If the affected Mortgage Loan is to be substituted for, the Master Servicer shall designate the Collection Account as the account to which funds in the amount of the Substitution Shortfall Amount are to be wired. Any such repurchase or substitution of a Mortgage Loan shall be on a whole loan, servicing released basis. Monthly Payments due with respect to each Qualified Substitute Mortgage Loan (if any) after the related Due Date in the month of substitution, and Monthly Payments due with respect to each Mortgage Loan being repurchased or replaced after the related Cut-Off Date and received by the Master Servicer or the Special Servicer on behalf of the Trust on or prior to the related date of repurchase or substitution, shall be part of the Trust Fund. Monthly Payments due with respect to each Qualified Substitute Mortgage Loan (if any) on or prior to the related Due Date in the month of substitution, and Monthly Payments due with respect to each Mortgage Loan being

-113-

repurchased or replaced and received by the Master Servicer or the Special Servicer on behalf of the Trust after the related date of repurchase or substitution, shall not be part of the Trust Fund and are to be remitted by the Master Servicer to the Mortgage Loan Seller effecting the related repurchase or substitution promptly following receipt.

If the Special Servicer or the Depositor receives a Repurchase Communication of a withdrawal of a Repurchase Request of which notice has been previously received or given and which withdrawal is by the Person making such Repurchase Request (a “Repurchase Request Withdrawal”), such party shall give written notice of such Repurchase Request Withdrawal to the applicable Mortgage Loan Seller, the other parties hereto, the Controlling Class Representative (prior to the occurrence and continuance of a Consultation Termination Event), any Companion Loan Holder (if applicable) and, for posting to the Rule 17g-5 Information Provider’s Website pursuant to Section 11.13 of this Agreement, the Rule 17g-5 Information Provider (to the extent notice has not previously been delivered to such Persons pursuant to this sentence). If the Special Servicer receives a Repurchase Communication that any Mortgage Loan that was subject of a Repurchase Request has been repurchased or replaced (a “Repurchase”), or that such Repurchase Request has been rejected (a “Repurchase Request Rejection”), then the Special Servicer shall (in accordance with the following paragraph) give written notice of such Repurchase or Repurchase Request Rejection to the Depositor, the applicable Mortgage Loan Seller unless it is the entity that has repurchased or replaced the subject Mortgage Loan or rejected such Repurchase Request, and unless it is the party that notified the Special Servicer thereof, the Certificate Administrator and the Trustee.

Each notice of a Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection required to be given by a party pursuant to this Section 2.03(a) (each, a “15Ga-1 Notice”) shall be given no later than ten (10) Business Days after receipt of a Repurchase Communication of such Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection, as applicable, and shall include (i) the identity of the related Mortgage Loan, (ii) the date that the Repurchase Communication regarding the Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection was received, as applicable, (iii) if known, the basis for the Repurchase Request (as asserted in the Repurchase Request) and (iv) in the case of 15Ga-1 Notices provided by the Special Servicer with respect to a Repurchase Request, a statement as to whether the Special Servicer currently plans to pursue such Repurchase Request.

If the Trustee, the Certificate Administrator, the Master Servicer, the Operating Advisor or the Custodian receives a Repurchase Communication of a Repurchase Request, a Repurchase Request Withdrawal, a Repurchase or a Repurchase Request Rejection, then such party shall promptly forward such Repurchase Communication of such Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection to the Special Servicer (with respect to any Mortgage Loan or REO Mortgage Loan) and, with respect to any Mortgage Loan, prior to the occurrence and continuance of a Consultation Termination Event, the Controlling Class Representative, and include the following statement in the related correspondence: “This is a Repurchase Communication regarding [a “Repurchase Request”] [a “Repurchase Request Withdrawal”] [a “Repurchase”] [a “Repurchase Request Rejection”] under Section 2.03(a) of the Pooling and Servicing Agreement relating to the CSAIL 2015-C4 Commercial Mortgage Trust, Commercial Mortgage Pass Through Certificates, Series 2015-C4,

-114-

requiring action by you as the recipient of such [Repurchase Request] [Repurchase Request Withdrawal] [Repurchase] [Repurchase Request Rejection] thereunder”. Upon receipt of any Repurchase Communication of a Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection by the Special Servicer pursuant to the foregoing provisions of this paragraph, the Special Servicer shall be deemed to be the recipient of such Repurchase Communication of such Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection, and the Special Servicer shall comply with the notice procedures set forth in the preceding paragraphs of this Section 2.03(a) with respect to such Repurchase Communication of such Repurchase Request, Repurchase Request Withdrawal, Repurchase or Repurchase Request Rejection.

No Person that is required to provide a 15Ga-1 Notice pursuant to this Section 2.03(a) (a “15Ga-1 Notice Provider”) shall be required to provide any information in a 15Ga-1 Notice protected by the attorney-client privilege or attorney work product doctrines. Each Loan Purchase Agreement will provide that (i) any 15Ga-1 Notice provided pursuant to this Section 2.03(a) is so provided only to assist the related Mortgage Loan Seller, the Depositor and their respective Affiliates to comply with Rule 15Ga-1, Items 1104 and 1121 of Regulation AB and any other requirement of law or regulation and (ii)(A) no action taken by, or inaction of, a 15Ga-1 Notice Provider and (B) no information provided pursuant to this Section 2.03(a) by a 15Ga-1 Notice Provider in a 15Ga-1 Notice shall be deemed to constitute a waiver or defense to the exercise of any legal right the 15Ga-1 Notice Provider may have with respect to the related Loan Purchase Agreement, including with respect to any Repurchase Request that is the subject of a 15Ga-1 Notice.

On or before the Closing Date, the Depositor shall deliver to the Master Servicer a copy of each Loan Purchase Agreement, which the Master Servicer shall provide to each Sub-Servicer.

With respect to any Non-Serviced Mortgage Loan, the parties to this Agreement agree that if a “material document defect” exists with respect to the related Non-Serviced Companion Loan under the Other Pooling and Servicing Agreement that governs servicing of the related Whole Loan and the related Mortgage Loan Seller (or other responsible repurchasing entity) repurchases such related Companion Loan pursuant to or as contemplated by such Other Pooling and Servicing Agreement, then such Mortgage Loan Seller shall also repurchase such Non-Serviced Mortgage Loan; provided, however, that such repurchase obligation does not apply to any “material document defect” related solely to the promissory note for such Companion Loan.

(b) Subject to the applicable Mortgage Loan Seller’s right to cure as contemplated in this Section 2.03, and further subject to Section 2.01(b) and Section 2.01(c) of this Agreement, failure of such Mortgage Loan Seller to deliver the documents referred to in clauses (1), (2), (7), (8), (18) and (19) in the definition of “Mortgage File” in accordance with this Agreement and the applicable Loan Purchase Agreement for any Mortgage Loan shall be deemed a Material Document Defect; provided, however, that no Document Defect (except a deemed Material Document Defect described above and except a Material Document Defect that causes any Mortgage Loan to fail to be a “qualified mortgage” within the meaning of Code Section 860G(a)(3)) shall be considered to be a Material Document Defect unless the document

-115-

with respect to which the Document Defect exists is required in connection with an imminent enforcement of the lender’s rights or remedies under the related Mortgage Loan, defending any claim asserted by any Mortgagor or third party with respect to the Mortgage Loan, establishing the validity or priority of any lien on any collateral securing the Mortgage Loan or for any immediate significant servicing obligation.

(c) In connection with any repurchase of, or substitution of a Qualified Substitute Mortgage Loan for, a Mortgage Loan pursuant to this Section 2.03, the Trustee, the Certificate Administrator, the Custodian, the Master Servicer and the Special Servicer shall each tender to the applicable Mortgage Loan Seller, upon delivery to each of them of a receipt executed by the applicable Mortgage Loan Seller evidencing such repurchase or substitution, all portions of the Mortgage File and other documents (including, without limitation, the Servicing File), and all escrows and reserve funds, pertaining to such Mortgage Loan possessed by it, and each document that constitutes a part of the Mortgage File shall be endorsed or assigned to the extent necessary or appropriate to the applicable Mortgage Loan Seller or its designee in the same manner, but only if the respective documents have been previously assigned or endorsed to the Trustee, and pursuant to appropriate forms of assignment, substantially similar to the manner and forms pursuant to which such documents were previously assigned to the Trustee or as otherwise reasonably requested to effect the retransfer and reconveyance of the Mortgage Loan and the security thereof to the Mortgage Loan Seller or its designee; provided that such tender by the Trustee and the Custodian shall be conditioned upon its receipt (and such receipt shall be deemed to be the Master Servicer’s direction to the Trustee and the Custodian to so tender) from the Master Servicer of a Request for Release and an Officer’s Certificate to the effect that the requirements for repurchase or substitution have been satisfied. The Master Servicer shall, and is hereby authorized and empowered by the Trustee to, prepare, execute and deliver in its own name, on behalf of the Certificateholders and the Trustee or any of them, the endorsements and assignments contemplated by this Section 2.03(c), and such other instruments as may be necessary or appropriate to transfer title to an REO Property (including with respect to a Non-Serviced Mortgage Loan) in connection with the repurchase of, or substitution for, an REO Mortgage Loan and the Trustee shall execute and deliver any powers of attorney necessary to permit the Master Servicer to do so; provided, however, that the Trustee shall not be held liable for any misuse of any such power of attorney by the Master Servicer or any of its agents or subcontractors.

(d) The related Loan Purchase Agreement provides the sole remedies available to the Certificateholders, or the Certificate Administrator or the Trustee on behalf of the Certificateholders, respecting any Document Defect or Breach with respect to any Mortgage Loan.

(e) If (i) any Crossed Underlying Loan is required to be repurchased or substituted for in the manner described in this Section 2.03 and (ii) the applicable Defect or Breach does not constitute a Defect or Breach, as the case may be, as to any other Crossed Underlying Loan in the related Crossed Mortgage Loan Group (without regard to this paragraph), then the applicable Defect or Breach, as the case may be, will be deemed to constitute a Defect or Breach, as the case may be, as to any other Crossed Underlying Loan in the related Crossed Mortgage Loan Group for purposes of this paragraph, and the related Mortgage Loan Seller will be required to repurchase or substitute for such other Crossed

-116-

Underlying Loan(s) in the related Crossed Mortgage Loan Group as provided in Section 2.03(a) unless such other Crossed Underlying Loans satisfy the Crossed Underlying Loan Repurchase Criteria. In the event that the remaining Crossed Underlying Loans in such Crossed Mortgage Loan Group satisfy the aforementioned criteria, the applicable Mortgage Loan Seller may elect either to repurchase or substitute for only the affected Crossed Underlying Loan(s) as to which the related Breach or Defect exists or to repurchase or substitute for all of the Crossed Underlying Loans in the related Crossed Mortgage Loan Group. Any reserve or other cash collateral or letters of credit securing the Crossed Underlying Loans shall be allocated among the related Crossed Underlying Loans in accordance with the related Mortgage Loan documents or otherwise on a pro rata basis based upon their outstanding Stated Principal Balances. Except as provided in this Section 2.03(e) and Section 2.03(f), all other terms of the related Mortgage Loans shall remain in full force and effect without any modification thereof.

(f) Notwithstanding the foregoing, if the related Mortgage provides for the partial release of one or more of the Crossed Underlying Loans, the Depositor may cause the related Mortgage Loan Seller to repurchase only that Crossed Underlying Loan required to be repurchased pursuant to this Section 2.03, pursuant to the partial release provisions of the related Mortgage; provided, however, that (i) the remaining related Crossed Underlying Loan(s) fully comply with the terms and conditions of the related Mortgage, this Agreement and the related Mortgage Loan Purchase Agreement, including the Crossed Underlying Loan Repurchase Criteria, (ii) in connection with such partial release, the related Mortgage Loan Seller obtains an Opinion of Counsel (at such Mortgage Loan Seller’s expense) to the effect that the contemplated action will not cause either Trust REMIC to fail to qualify as a REMIC, or result in the imposition of any tax on either Trust REMIC and (iii) in connection with such partial release, the related Mortgage Loan Seller delivers or causes to be delivered to the Custodian original modifications to the Mortgage prepared and executed in connection with such partial release.

(g) With respect to any Crossed Underlying Loan, to the extent that the applicable Mortgage Loan Seller is required to repurchase or substitute for such Crossed Underlying Loan in the manner prescribed in Section 2.03(a) while the Trustee continues to hold any other Crossed Underlying Loans in the related Crossed Mortgage Loan Group, the applicable Mortgage Loan Seller and the Master Servicer or, with respect to a Specially Serviced Mortgage Loan, the Special Servicer, on behalf of the Trustee, as assignee of the Depositor, will, as set forth in the related Mortgage Loan Purchase Agreement, forbear from enforcing any remedies against the other’s Primary Collateral but each will be permitted to exercise remedies against the Primary Collateral securing its respective related Mortgage Loans, including with respect to the Trustee, the Primary Collateral securing the Mortgage Loans still held by the Trustee, so long as such exercise does not materially impair the ability of the other party to exercise its remedies against its Primary Collateral. If the exercise of the remedies by one party would materially impair the ability of the other party to exercise its remedies with respect to the Primary Collateral securing the Crossed Underlying Loans held by such party, then both parties have agreed in the related Mortgage Loan Purchase Agreement to forbear from exercising such remedies until the Mortgage Loan documents evidencing and securing the relevant Mortgage Loan can be modified in a manner that complies with the related Mortgage Loan Purchase Agreement to remove the threat of material impairment as a result of the exercise of remedies.

If with respect to any Mortgage Loan (or Serviced Whole Loan) the related Mortgage Loan Documents permit the lender to (but do not require the lender to), at its option, prior to an event of default under the related Mortgage Loan (or Serviced Whole Loan), apply amounts held in any reserve account as a prepayment or hold such amounts in a reserve account, the Master Servicer shall not apply such amounts as prepayment, and instead shall hold such amounts in the applicable reserve account and may not apply such amounts as a prepayment until the occurrence of an event of default under the related Mortgage Loan (or Serviced Whole Loan); provided that any such amounts may be used, if permitted under the related Mortgage Loan Documents, to defease the related Mortgage Loan (or Serviced Whole Loan) or, upon an event of default under the related Mortgage Loan (or Serviced Whole Loan), to prepay the Mortgage Loan (or Serviced Whole Loan).

(c) The Master Servicer may enter into Sub-Servicing Agreements with third parties with respect to any of its obligations hereunder, provided that (i) any such agreement shall be consistent with the provisions of this Agreement, (ii) any such agreement shall be consistent with the Servicing Standard, (iii) the Depositor has consented to the related Sub-Servicer, (iv) any such agreement shall provide that, following receipt of the applicable Loan Purchase Agreement from the Depositor, the Master Servicer shall provide a copy of the applicable Loan Purchase Agreement to the related Sub-Servicer, and that such Sub-Servicer

-130-

shall notify the Master Servicer in writing within five (5) Business Days after such Sub-Servicer discovers or receives notice alleging a Document Defect or a Breach or receives a Repurchase Communication of a Repurchase Request, a Repurchase Request Withdrawal, a Repurchase or a Repurchase Request Rejection, (v) with respect to any Sub-Servicing Agreement entered into after the Closing Date, if such Sub-Servicer is a Servicing Function Participant or an Additional Servicer, such Sub-Servicer, at the time the related Sub-Servicing Agreement is entered into, is not a Prohibited Party and (vi) the Master Servicer shall notify the applicable Mortgage Loan Seller of any such agreement. Any such Sub-Servicing Agreement may permit the Sub-Servicer to delegate its duties to agents or subcontractors so long as the related agreements or arrangements with such agents or subcontractors are consistent with the provisions of this Section 3.01(c). The Master Servicer shall pay the servicing fees of any Sub-Servicer and shall provide a copy of each Sub-Servicing Agreement (and any assignment thereof) to the Trustee. Any Sub-Servicing Agreement entered into by the Master Servicer shall provide that it may be assumed by the Trustee, if the Trustee has assumed the duties of the Master Servicer or by any successor Master Servicer without cost or obligation to the assuming party or the Trust Fund, upon the assumption by such party of the obligations of the Master Servicer pursuant to Section 7.02. The Special Servicer may not enter into Sub-Servicing Agreements; provided that, if and to the extent Midland Loan Services, a Division of PNC Bank, National Association or its successor-in-interest is terminated as Special Servicer by the Controlling Class Representative without cause (i.e., not as a result of a Servicer Termination Event) and Midland Loan Services, a Division of PNC Bank, National Association or its successor-in-interest otherwise satisfies all of the eligibility requirements applicable to special servicers contained in this Agreement, Midland Loan Services, a Division of PNC Bank, National Association or its successor-in-interest may be appointed as a sub-special servicer of a successor Special Servicer appointed by the Controlling Class Representative, subject to the consent of the Controlling Class Representative.

Any Sub-Servicing Agreement, and any other transactions or services relating to the Mortgage Loans and/or Serviced Whole Loans involving a Sub-Servicer, shall be deemed to be between the Master Servicer and such Sub-Servicer alone, and the Trustee, the Certificate Administrator, the Custodian, the Operating Advisor, the Trust Fund and the Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Sub-Servicer, except as set forth in Section 3.01(d) of this Agreement and no provision herein may be construed so as to require the Trust Fund to indemnify any such Sub-Servicer.

(d) If the Trustee or any successor Master Servicer assumes the obligations of the Master Servicer in accordance with Section 7.02, the Trustee or such successor, as applicable, to the extent necessary to permit the Trustee or such successor, as applicable, to carry out the provisions of Section 7.02, shall, without act or deed on the part of the Trustee or such successor, as applicable, succeed to all of the rights and obligations of the Master Servicer under any Sub-Servicing Agreement entered into by the Master Servicer pursuant to Section 3.01(c) of this Agreement. In such event, the Trustee or the successor Master Servicer, as applicable, shall be deemed to have assumed all of the Master Servicer’s interest therein (but not any liabilities or obligations in respect of acts or omissions of the Master Servicer prior to such deemed assumption) and to have replaced the Master Servicer as a party to such Sub-Servicing Agreement to the same extent as if such Sub-Servicing Agreement had been assigned to the

-131-

Trustee or such successor Master Servicer, as applicable, except that the Master Servicer shall not thereby be relieved of any liability or obligations under such Sub-Servicing Agreement that accrued prior to the succession of the Trustee or the successor Master Servicer, as applicable.

In the event that the Trustee or any successor Master Servicer, assumes the servicing obligations of the Master Servicer, upon request of the Trustee, or such successor Master Servicer, as applicable, the Master Servicer shall at its own expense deliver or cause to be delivered to the Trustee or such successor Master Servicer all documents and records relating to any Sub-Servicing Agreement and the Mortgage Loans then being serviced thereunder and an accounting of amounts collected and held by it, if any, and will otherwise use its reasonable efforts to effect the orderly and efficient transfer of any Sub-Servicing Agreement to the Trustee or the successor Master Servicer, as applicable.

(e) The parties hereto acknowledge that each Serviced Whole Loan is subject to the terms and conditions of the related Co-Lender Agreement and recognize the respective rights and obligations of the Trust, as holder of the related Mortgage Loan, and of the related Companion Loan Holder, including: (i) with respect to the allocation of collections on or in respect of such Whole Loan, and the making of remittances, to the Trust, as holder of the related Mortgage Loan, and to the related Companion Loan Holder(s); (ii) with respect to the allocation of expenses and losses relating to such Whole Loan to the Trust, as holder of the related Mortgage Loan, and to the related Companion Loan Holders; and (iii) the consultation rights of the related Companion Loan Holder or its Companion Loan Holder Representative. With respect to any Serviced Whole Loan, the Master Servicer (if such Serviced Whole Loan is a non-Specially Serviced Loan) or the Special Servicer (if such Serviced Whole Loan has become a Specially Serviced Loan or the related Mortgaged Property has been converted to an REO Property) shall (i) prepare and provide to such Companion Loan Holder all notices, reports, statements and communications to be delivered by the holder of the related Mortgage Loan under the related Co-Lender Agreement; and (ii) perform all duties and obligations to be performed by a servicer and perform all servicing-related duties and obligations to be performed by the holder of the related Mortgage Loan pursuant to the related Co-Lender Agreement and/or as set forth herein. All provisions required to be included herein by the related Co-Lender Agreement are deemed included and shall be enforceable to the same extent as if set forth herein. In the event of any conflict between this Agreement and a Co-Lender Agreement, the terms of such Co-Lender Agreement shall control with respect to the related Serviced Whole Loan.

(f) Notwithstanding anything to the contrary herein, (a) at no time shall the Master Servicer or the Trustee be required to make any P&I Advance on any Companion Loan and (b) if the Mortgage Loan (or the related REO Property) that is part of a Serviced Whole Loan is no longer part of the Trust Fund, neither the Master Servicer nor the Trustee, as the case may be, shall have any obligation to make any Property Advance on such Serviced Whole Loan. If pursuant to the foregoing sentence, the Master Servicer or the Trustee does not intend to make a Property Advance with respect to a Serviced Whole Loan that the Master Servicer or the Trustee would have made if the related Mortgage Loan or REO Property were still part of the Trust Fund, the Master Servicer or the Trustee, as the case may be, shall promptly notify the holder of the related Companion Loan of its intention to no longer make such Property Advances and shall additionally promptly notify such holder of any required Property Advance it would have otherwise made upon becoming aware of the need for such Property Advance. Additionally, at

-132-

the time the Mortgage Loan relating to a Serviced Whole Loan is removed from the Trust Fund, the Master Servicer or the Trustee, as the case may be, shall deliver to the related Companion Loan Holder (or the master servicer of any securitization of the related Companion Loan) (i) a copy of the most recent inspection report and the inspection report for the prior calendar year, (ii) copies of all financial statements collected from the related Mortgagor for the most recent calendar year and the prior calendar year, (iii) a copy of the most recent Appraisal and any other Appraisal done in the prior year and (iv) a copy of all tax and insurance bills for the current calendar year and the prior calendar year.

(g) With respect to the Mortgage Loans set forth on Exhibit HH, to the extent required under any Mortgage Loan Documents, the Master Servicer shall, on behalf of the related lender, maintain a Note register for the related Mortgage Loan in accordance with such Mortgage Loan Documents.

(h) Notwithstanding anything herein to the contrary, the parties hereto acknowledge and agree that the Master Servicer’s and the Special Servicer’s obligations and responsibilities hereunder and the Master Servicer’s and the Special Servicer’s authority with respect to any Non-Serviced Mortgage Loan and any Non-Serviced Companion Loan related to such Non-Serviced Mortgage Loan are limited by and subject to the terms of the related Co-Lender Agreement and this Agreement and the rights of an Other Master Servicer and an Other Special Servicer with respect thereto under the applicable Other Pooling and Servicing Agreement. The parties further recognize the respective rights and obligations of an Other Trustee and/or the related Companion Loan Holders (or the representatives thereof) under each respective Co-Lender Agreement including with respect to (i) the allocation of collections on or in respect of a Non-Serviced Whole Loan in accordance with the related Co-Lender Agreement, (ii) the purchase of a Non-Serviced Whole Loan or related Non-Serviced Mortgage Loan by the related Non-Serviced Companion Loan Holder or their designees in accordance with the respective Co-Lender Agreement to the extent provided therein and (iii) any cure rights that a Non-Serviced Companion Loan Holder may exercise, if applicable, in accordance with the related Co-Lender Agreement. The Trustee shall cooperate with the Master Servicer in connection with the enforcement of the rights by the Trustee on behalf of the Trust (as holder of each Non-Serviced Mortgage Loan) under each related Co-Lender Agreement and each applicable Other Pooling and Servicing Agreement. The Master Servicer (with the cooperation of and under the power of attorney granted by, the Trustee) shall take such actions as it shall deem reasonably necessary to facilitate the servicing of the related Non-Serviced Companion Loan by the related Other Master Servicer and the related Other Special Servicer, including, but not limited to, delivering appropriate requests for release to the custodian (if any) in order to deliver any portion of the related Mortgage Files to the related Other Master Servicer or Other Special Servicer under the applicable Other Pooling and Servicing Agreement.

To the extent that the Trust, as holder of a Non-Serviced Mortgage Loan for the benefit of the Certificateholders, is entitled to consult regarding, to consent to or approve any modification, waiver or amendment of, or other loan level action related to, such Non-Serviced Mortgage Loan, such consultation, consent or approval rights shall be exercised by the Controlling Class Representative or Operating Advisor, as applicable, as provided in Section 3.01(j) and Section 3.24(i), subject to the consent and/or consultation rights any other applicable Person, as provided in such Sections.

-133-

In addition to such consultation, consent or approval rights, the Controlling Class Representative (if no Control Termination Event has occurred and is continuing) and the Operating Advisor (if a Control Termination Event has occurred and is continuing), on behalf of the Trust, as holder of a Non-Serviced Mortgage Loan for the benefit of the Certificateholders, will have the right (exercisable in its sole discretion), to the extent provided in the related Co-Lender Agreement and/or the applicable Other Pooling and Servicing Agreement, to attend (in-person or telephonically) annual meetings with the related Other Master Servicer or Other Special Servicer, as applicable, upon reasonable notice and at times reasonably acceptable to the related Other Master Servicer or Other Special Servicer, as applicable, for the purpose of discussing servicing issues related to the Non-Serviced Mortgage Loan.

None of the Master Servicer, the Special Servicer, the Operating Advisor, the Certificate Administrator or the Trustee shall have any obligation or authority to supervise any Other Master Servicer, any Other Special Servicer, any Other Operating Advisor, any Other Certificate Administrator, any Other Trustee or any other party to the applicable Other Pooling and Servicing Agreement or to make Property Advances with respect to a Non-Serviced Mortgage Loan or a Non-Serviced Companion Loan related to such Non-Serviced Mortgage Loan. The obligation of the Master Servicer and the Special Servicer to provide information to the Certificate Administrator, the Trustee or any other Person with respect to a Non-Serviced Mortgage Loan and any Non-Serviced Companion Loan related to such Non-Serviced Mortgage Loan is dependent on their receipt of the corresponding information from an Other Master Servicer or an Other Special Servicer, as applicable.

(i) The parties hereto acknowledge that the Non-Serviced Whole Loan is subject to the terms and conditions of the related Co-Lender Agreement and further acknowledge that, pursuant to the related Co-Lender Agreement, (i) the related Non-Serviced Mortgage Loan and Non-Serviced Companion Loan are to be serviced and administered by an Other Master Servicer and Other Special Servicer in accordance with the applicable Other Pooling and Servicing Agreement, and (ii) in the event that the applicable Non-Serviced Companion Loan is no longer part of the trust fund created by the applicable Other Pooling and Servicing Agreement and the related Non-Serviced Mortgage Loan remains an asset of the Trust Fund, then, as set forth in the related Co-Lender Agreement, the related Whole Loan shall be serviced in accordance with the applicable provisions of the applicable Other Pooling and Servicing Agreement as if such agreement was still in full force and effect with respect to the related Whole Loan, until such time as a new servicing agreement has been agreed to by the parties to the related Co-Lender Agreement in accordance with the provisions of such agreement and confirmation has been obtained from the Rating Agencies that such new servicing agreement would not result in a downgrade, qualification or withdrawal of the then-current ratings of any Class of Certificates then-outstanding and any other requirements applicable to the related Non-Serviced Mortgage Loan.

(j) The parties hereto acknowledge that the Non-Serviced Mortgage Loan is subject to the terms and conditions of the related Co-Lender Agreement. The parties hereto recognize the respective rights and obligations of the “Initial Note Holders” and “Note Holders” under the related Co-Lender Agreement for such Non-Serviced Mortgage Loan, including with respect to the allocation of collections and losses on or in respect of such Non-Serviced Mortgage Loan and the related Non-Serviced Companion Loan and the making of payments to

-134-

the “Initial Note Holders” and “Note Holders” in accordance with such Co-Lender Agreement and the Other Pooling and Servicing Agreement. The parties hereto further acknowledge that, pursuant to the related Co-Lender Agreement, the Non-Serviced Mortgage Loan and the related Non-Serviced Companion Loan are to be serviced and administered by the related Other Master Servicer and the related Other Special Servicer in accordance with the related Other Pooling and Servicing Agreement. Although the Non-Serviced Mortgage Loan is not serviced and administered hereunder, the Master Servicer and the Special Servicer hereunder for each such Non-Serviced Mortgage Loan shall have certain duties as set forth herein and shall constitute the “Master Servicer” and “Special Servicer” hereunder with respect to such Non-Serviced Mortgage Loan.

If there are at any time amounts due from the Trust, as holder of the Non-Serviced Mortgage Loan, to any party under the related Co-Lender Agreement or the applicable Other Pooling and Servicing Agreement, the Master Servicer shall pay such amounts out of the Collection Account. If a party to the applicable Other Pooling and Servicing Agreement related to a Non-Serviced Mortgage Loan requests the Master Servicer, Special Servicer, Trustee, Certificate Administrator or Custodian to consult regarding, consent to or approve a modification, waiver or amendment of, or other loan-level action related to, such Non-Serviced Mortgage Loan (and a modification, waiver or amendment of the applicable Other Pooling and Servicing Agreement and/or the related Co-Lender Agreement shall not be subject to the operation of this sentence but shall instead be subject to the operation of the second succeeding sentence), then the Master Servicer shall promptly forward any such request it receives to the Special Servicer and the Special Servicer shall promptly deliver a copy of such request it receives (from the Master Servicer or directly from a party to the applicable Other Pooling and Servicing Agreement) to the Controlling Class Representative (with respect to any consent rights, if no Control Termination Event has occurred and is continuing, and with respect to any consultation rights, if no Consultation Termination Event has occurred) or the Operating Advisor (with respect to any consultation rights, if a Consultation Termination Event has occurred), and the Controlling Class Representative or Operating Advisor (as applicable) shall exercise such right of consultation or consent, as applicable, as provided in Section 3.24(i); provided, however, that (i) insofar as any other Person (including without limitation the Controlling Class Representative or the Operating Advisor) would have consent and/or consultation rights hereunder with respect to a similar modification, waiver or amendment of, or other loan level action related to, a Mortgage Loan that is a Serviced Mortgage Loan, such Person shall likewise have the same consent and/or consultation rights, subject to the same procedures, conditions and/or restrictions, with respect to such modification, waiver or amendment of, or other loan level action related to, such Non-Serviced Mortgage Loan as set forth in this Agreement and (ii) if such Non-Serviced Mortgage Loan were serviced hereunder and such action would not be permitted without Rating Agency Confirmation, then the Controlling Class Representative shall not exercise such right of consent without first having received such Rating Agency Confirmation (payable at the expense of the party requesting such approval, if a Certificateholder or a party to this Agreement, otherwise from the Collection Account). If a Responsible Officer of the Trustee receives actual notice of a “servicer termination event” under the applicable Other Pooling and Servicing Agreement, then the Trustee shall notify the Master Servicer, the Special Servicer and the Controlling Class Representative (in writing), and the Master Servicer or the Special Servicer, as applicable, shall instruct the Other Trustee to terminate the Other Master Servicer or Other Special Servicer, as applicable, if so directed in writing by the Controlling

-135-

Class Representative (prior to the occurrence of a Control Termination Event) (provided that the Master Servicer and the Special Servicer shall only be required to comply with such instructions if such instructions are in accordance with the applicable Other Pooling and Servicing Agreement and not inconsistent with this Agreement); provided that, if such instructions are not provided within a reasonable time period (not to exceed ten (10) Business Days or such lesser response time as is afforded under the applicable Other Pooling and Servicing Agreement) or if the Master Servicer or Special Servicer, as applicable, is not permitted by the applicable Other Pooling and Servicing Agreement to follow such instructions or if a Control Termination Event has occurred, then the Master Servicer or Special Servicer, as applicable, shall instruct the Other Trustee to terminate the Other Master Servicer or Other Special Servicer, as applicable (to the extent permitted by the applicable Other Pooling and Servicing Agreement), if so directed in writing by the Holders of the Certificates entitled to a majority of the Voting Rights (such direction communicated to the Master Servicer or Special Servicer, as applicable, by the Certificate Administrator upon receipt) within a reasonable period of time that does not exceed such response time as is afforded under the applicable Other Pooling and Servicing Agreement. If the Trustee receives a written request from any party to the applicable Other Pooling and Servicing Agreement for consent to or approval of a modification, waiver or amendment of the applicable Other Pooling and Servicing Agreement and/or the related Co-Lender Agreement, or the adoption of any servicing agreement that is the successor to and/or in replacement of the applicable Other Pooling and Servicing Agreement in effect as of the Closing Date or a change in servicer under the applicable Other Pooling and Servicing Agreement, then the Trustee (if it shall have received a prior Rating Agency Confirmation from each Rating Agency (at the expense of the party requesting such approval of the Trustee, if a Certificateholder or a party to this Agreement and otherwise from the Collection Account) with respect to such consent or approval) shall grant such consent or approval; provided that unless a Control Termination Event has occurred and is continuing, the Trustee shall obtain the consent of the Controlling Class Representative prior to granting any such consent. The Trustee shall not take any action and shall not be liable for failing to take any action except upon obtaining such consent and direction. Prior to granting or withholding any such consent, the Trustee shall not take any action and shall not be liable for failing to take any action except upon obtaining such consent and direction. During the continuation of any termination event under the applicable Other Pooling and Servicing Agreement, each of the Trustee, the Master Servicer and the Special Servicer shall have the right (but not the obligation) to take all actions to enforce its rights and remedies and to protect the interests, and enforce the rights and remedies, of the Trust (including the institution and prosecution of all judicial, administrative and other proceedings and the filings of proofs of claim and debt in connection therewith). The reasonable costs and expenses incurred by the Master Servicer, Special Servicer or the Trustee in connection with such enforcement shall be paid by the Master Servicer out of the Collection Account. The Trustee, the Special Servicer and the Master Servicer shall each promptly forward all material notices or other communications delivered to it in connection with the applicable Other Pooling and Servicing Agreement to the other such party, the Depositor and (prior to the occurrence of a Consultation Termination Event) the Controlling Class Representative and, if such notice or communication is in the nature of a notice or communication that would be required to be delivered to the Rule 17g-5 Information Provider (for posting to the Rule 17g-5 Information Provider’s Website in accordance with Section 11.13) if the related Non-Serviced Mortgage Loan were a Mortgage Loan that is serviced and administered under this Agreement, to the Rule 17g-5 Information Provider (who shall

-136-

promptly post such notice to the Rule 17g-5 Information Provider’s Website in accordance with Section 11.13). Any obligation of the Master Servicer or Special Servicer, as applicable, to provide information and collections to the Trustee, the Certificate Administrator, the Controlling Class Representative and the Certificateholders with respect to any Non-Serviced Mortgage Loan shall be dependent on its receipt of the corresponding information and collections from the applicable Other Master Servicer or the applicable Other Special Servicer. Each of the Trustee, the Certificate Administrator, the Master Servicer and the Special Servicer shall reasonably cooperate with the Controlling Class Representative or the Operating Advisor, as applicable, to facilitate the exercise by the Controlling Class Representative or the Operating Advisor, as applicable, of any consent, approval or consultation rights set forth in this Section 3.01(j); provided, however, that the Trustee, the Certificate Administrator, the Master Servicer and Special Servicer shall have no right or obligation to exercise any consent or consultation rights or obtain a Rating Agency Confirmation on behalf of the Controlling Class Representative.

(k) With respect to any Non-Serviced Mortgage Loan, the parties to this Agreement agree as follows:

(i) pursuant to the applicable Other Pooling and Servicing Agreement, the related Other Master Servicer is obligated to make “Property Advances” and incur “Additional Trust Fund Expenses” (or such other similar term, each as defined in the applicable Other Pooling and Servicing Agreement) with respect to any Non-Serviced Mortgage Loan; the Trust shall be responsible for its pro rata share of any “Nonrecoverable Servicing Advances” (and accrued and unpaid interest thereon) and any “Additional Trust Fund Expenses” (but not any interest on “P&I Advances”) (each as defined in the applicable Other Pooling and Servicing Agreement), but only to the extent that they relate to servicing and administration of a Non-Serviced Mortgage Loan, including without limitation, any unpaid “Special Servicing Fees”, “Liquidation Fees” and “Workout Fees” (each as defined in the applicable Other Pooling and Servicing Agreement) relating to a Non-Serviced Mortgage Loan; and in the event that the funds received with respect to any Non-Serviced Whole Loan are insufficient to cover “Property Advances” or “Additional Trust Fund Expenses” (each as defined in the applicable Other Pooling and Servicing Agreement), (i) the Master Servicer shall, promptly following notice from the Other Master Servicer or the Other Special Servicer, pay or reimburse the Other Master Servicer, the Other Special Servicer, the Other Certificate Administrator or an Other Trustee, as applicable (such reimbursement, to the extent owed to an Other Special Servicer, an Other Certificate Administrator or an Other Trustee, may be paid by the Master Servicer to an Other Master Servicer, who shall pay such amounts to an Other Special Servicer, an Other Certificate Administrator or an Other Trustee, as applicable), out of general funds in the Collection Account for the Trust’s pro rata share of any such “Nonrecoverable Servicing Advances” (together with advance interest thereon) and/or “Additional Trust Fund Expenses” (each as defined in the applicable Other Pooling and Servicing Agreement)), and (ii) if the applicable Other Pooling and Servicing Agreement permits the Other Master Servicer, the Other Special Servicer, the Other Certificate Administrator or the Other Trustee to reimburse itself from the Other Securitization Trust’s general collections, then the parties to this Agreement hereby acknowledge and agree that the Other Master Servicer, the Other Special Servicer, the Other Certificate Administrator or the Other Trustee, as applicable, may do so and the

-137-

Master Servicer shall be required to, promptly following notice from the Other Master Servicer, the Other Special Servicer or the Other Trustee, reimburse the Other Securitization Trust out of general funds in the Collection Account for the Trust’s pro rata share of any such “Nonrecoverable Servicing Advances” (together with advance interest thereon) and/or “Additional Trust Fund Expenses” (each as defined in the applicable Other Pooling and Servicing Agreement);

(ii) any Other Securitization Trust and each of the parties to the applicable Other Pooling and Servicing Agreement shall be indemnified with respect to losses, costs and expenses relating to the related Non-Serviced Mortgage Loan as and to the same extent the Other Trust is required to indemnify each of such Persons in respect of other mortgage loans in the Other Trust pursuant to the terms of Other Pooling and Servicing Agreement by the Trust to the extent of the Trust’s pro rata share of any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liabilities, fees and expenses incurred in connection with the servicing and administration of the related Non-Serviced Mortgage Loan and the related Mortgaged Property under the related Other Pooling and Servicing Agreement, and to the extent amounts on deposit in the “Serviced Whole Loan Custodial Account” (or such other similar term, as defined in the applicable Other Pooling and Servicing Agreement) are insufficient for reimbursement of such amounts, the Master Servicer shall, promptly following notice from the related Other Master Servicer, reimburse each of such applicable Persons for the Trust’s pro rata share of the insufficiency out of general funds in the Collection Account;

(iii) in the event of a conflict between the provisions of this Agreement and the related Co-Lender Agreement, the related Co-Lender Agreement shall prevail; provided that in no event shall the Master Servicer or the Special Servicer, as the case may be, take any action or omit to take any action in accordance with the terms of any Co-Lender Agreement, that would cause the Master Servicer or the Special Servicer, as applicable, to violate the Servicing Standard or REMIC Provisions;

(iv) any provisions required to be included herein pursuant to the related Co-Lender Agreement are deemed included and shall be enforceable to the same extent as if set forth herein; and

(v) the Other Master Servicer, the Other Special Servicer, the Other Trustee and the Other Securitization Trust shall be third party beneficiaries of this Section 3.01(k).

Section 3.02 Liability of the Master Servicer. Notwithstanding any Sub-Servicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between the Master Servicer and any Person acting as Sub-Servicer (or its agents or subcontractors) or any reference to actions taken through any Person acting as Sub-Servicer or otherwise, the Master Servicer shall remain obligated and primarily liable for the servicing and administering of the Mortgage Loans (other than with respect to the primary servicing of any Non-Serviced Mortgage Loans) and the Serviced Companion Loans in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such

-138-

Sub-Servicing Agreements or arrangements or by virtue of indemnification from any Person acting as Sub-Servicer (or its agents or subcontractors) to the same extent and under the same terms and conditions as if the Master Servicer alone were servicing and administering the Mortgage Loans (other than with respect to the primary servicing of any Non-Serviced Mortgage Loans) and the Serviced Companion Loans. The Master Servicer shall be entitled to enter into an agreement with any Sub-Servicer providing for indemnification of the Master Servicer by such Sub-Servicer, and nothing contained in this Agreement shall be deemed to limit or modify such indemnification, but no such agreement for indemnification shall be deemed to limit or modify this Agreement.

For clarification, no obligation of the Master Servicer or the Special Servicer to use commercially reasonable efforts to collect fees from the related Mortgagor will change the obligation of the Master Servicer to pay such fees from general collections or other proceeds in accordance with Section 3.06(a) and 3.06A as applicable, of this Agreement, whether or not such Special Servicing Fees, Workout Fees or Liquidation Fees are collected from or paid by the related Mortgagor. The Master Servicer, with respect to the Mortgage Loans (other than any Non-Serviced Mortgage Loan) other than Specially Serviced Loans, and Special Servicer, with respect to the Specially Serviced Loans, shall use its reasonable efforts to collect operating statements, rent rolls and other reporting information from Mortgagors (as required under the related Mortgage Loan Documents); provided, that if the related Mortgage Loan documents permit the lender to request audited financial statements, the Master Servicer shall be required to request audited financial statements from the related Mortgagor. Consistent with the foregoing, the Master Servicer (with respect to non-Specially Serviced Loans) or Special Servicer (with respect to Specially Serviced Loans), as applicable, may in its discretion waive any Penalty Charges in connection with any delinquent Monthly Payment with respect to any Mortgage Loan or Companion Loan. In addition, the Master Servicer shall be entitled to take such actions with respect to the collection of payments on the Mortgage Loans and the Serviced Companion Loans as are permitted or required under this Section 3.03.

The Master Servicer shall, within two (2) Business Days of receipt of properly identified funds, deposit into the Collection Account all amounts received with respect to any Non-Serviced Mortgage Loan, the Mortgaged Property related to such Non-Serviced Mortgage Loan or any related REO Property.
